Force enableExclude to false when ExcludeNode "in"/"inout" is enabled on all keepNodes and newNodes

Currently in the adjustInitialSolutionIfNecessary function, enableExclude flag is set to falseusing the following condition

// if there is deleted node and all nodes are excluded to take in new indexes,// then do not enable node exclusion

if s.numDeletedNode != 0 && s.findNumExcludeInNodes() == len(s.Placement) {

      s.enableExclude = false

}

here the condition of checking should not be len(s.Placement) rather we will need to check if all the keepNodes & all the emptyNodes (considered to be newNodes by planner) has ExcludeNode "in" enabled. This is done as initially the solution will consider even the Nodes to be ejected/deleted in the Placement slice
